Description

technical field

[0001] The present application relates to the field of communication technology, in particular to a driving circuit and a driving method for a mobile phone with a metal back shell. Background technique

[0002] At present, for mobile phones with metal back shells, most parts of the back shell are divided into metals as antennas, so as to realize signal transmission between the mobile phone and the base station. Specifically as Figure 1a As shown, the metal part 11 is the upper end of the back shell of the mobile phone, and is mainly used for the overall support of the mobile phone. The metal part 12 is the lower end of the rear case of the mobile phone and is used as an antenna. At the same time, a plastic strip 13 is provided between the metal part 11 and the metal part 12 to play a connecting role.

[0003] At this time, in order to realize the antenna function of the metal component 12 , a metal connection bridge 14 is usually provided inside the plasti...
